About ME

﻿ Siva Nadimpalli received Bachelor’s degree in Mechanical Engineering from Andhra University (Vishakhapatnam, India) and Master’s degree in Mechanical Engineering from Indian Institute of Science (Bangalore, India). He worked for Wind Energy group at GE, Bangalore as a Mechanical Engineer from 2005 to 2006, and carried out projects involving fatigue analysis of wind turbine components and prototype testing of GE wind turbines. He moved to Canada in 2006 to pursue doctoral studies at University of Toronto. For his PhD, Siva Nadimpalli developed experimental techniques to characterize fracture behavior of solder joints and printed circuit boards in commercial microelectronic packages.

After finishing his PhD in January 2011, he joined Prof. Guduru’s group as a Postdoctoral research associate in School of Engineering at Brown University. The main focus of his research work was to understand the mechanical behavior of energy storage materials and to investigate how mechanics phenomena affect electrochemical performance of lithium-ion batteries, primarily by using various experimental techniques. In March 2013 he returned to Canada to work for Nanowave Technologies Inc. Toronto, where he supported both manufacturing and product development groups, and performed thermal and mechanical simulations (using finite element packages) to improve the reliability of the electronic devices by proposing designs for effective cooling and to avoid fracture/delamination. He joined NJIT in Fall 2013 as an assistant professor.

Research

Dr. Nadimpalli’s research interests are in the area of experimental solid mechanics at nano and microscale. The main focus of his lab will be to use either existing experimental techniques or to develop new techniques and methods to address some of the issues pertaining to the mechanics of interface fracture, degradation, and failure of materials.

Energy Storage:one of the current focuses of Dr. Nadimpalli’s research is to understand and characterize various degradation (or failure) mechanisms of next generation lithium-ion battery electrode materials. He is especially interested in the interface fracture, delamination, and thin film fracture.

Microelectronics Packaging: Dr. Nadimpalli also has an interest in the area of Microelectronics reliability. He developed experimental techniques to characterize the mixed-mode fracture behavior of solder joints and applied these properties to predict the failure of solder joints in commercial packages such as BGAs and CTBGAs. He is interested in understanding the interface fracture behavior of joints under high strain-rate conditions as well as the failure behavior of various other interfaces in a complex microelectronic package structure, which is one of the primary issues that affect the reliability of the package.
